How does an alluvial fan form?

• It forms where a stream enters an ocean or lake, slows down, and deposits sediments there over time.

• It forms where part of a meandering stream is cut off.

• It forms where a stream reaches a flat area of land, slows down, and deposits sediments there over time.

A river starts as a steep channel in the mountains. It then leaves the mountains and enters a flatter area of land. It meanders across a plain and then enters the ocean. Which of the following actions causes the deposition of sand at a delta?

• river water slowing as it enters the ocean

• salt water and fresh water mixing together

• ocean waves transporting sand toward land

Emily used a tray filled with dirt as a model of a stream. Emily poured water into the top of the tray and observed how much erosion happened. Emily then increased the slope of the tray and repeated the experiment. What would happen when the slope of the tray increased?

• The speed of the water and the amount of erosion would increase.

• The speed of the water and the amount of erosion would decrease.

• The speed of the water would increase, while the amount of erosion would decrease.
